AN/SPQ-9A (sometimes pronounced as "spook nine") is a United States Navy multi-purpose surface search and fire control radar used with the Mk-86 gun fire-control system (MK86 GFCS). It is a two dimensional surface-search radar, meaning it provides only range and bearing but …

AN/SPQ-9B是MK86炮火控制系统的探测器，是 反舰导弹 防御的 脉冲多普勒雷达，是水面搜索和目标捕获探测器。 它能对舰的横摆和纵摇稳定。 其主要特性：窄的仰角和方位波束宽度，可变的空中通道脉冲宽度，固定的水面通道脉冲宽度，动目标显示改善因子为80分贝，高扫描率。 关键功能：单次扫描检测和跟踪，现代超低噪声激励器，精致的检测和跟踪算法，空中/水面同时搜索和信标跟踪，广泛的机内测试。 此雷达的新天线垂直尺寸增加使垂直波束宽度变窄。 新的发射机 …

2021年11月15日 · The AN/SPQ-9B is an X-Band, pulse Doppler, frequency agile radar which was designed specifically for the littoral environment. It has a very high clutter improvement factor supporting a...

SPQ-9B型是SPQ-9A型的升级版，着重提升了探测掠海飞行、小雷达散射截面的巡航导弹的能力，可以在沿海地区和高杂波环境中使用。天线改用雙面接背式的電子掃描陣列雷達，旋转扫描频率为每分钟30转，有对空、对海和信标应答（beacon）三种模式。

AN/SPQ-9B 是一种多波形、窄波束、X 波段、脉冲多普勒雷达，它采用了 AN/APG-68机载火控雷达的发射机，设计用于 Mk86 舰炮火控系统 中替代 AN/SPQ-9A，或者作为独立设备使用。 该雷达的研发与采购过程大致为：20 世纪 80 年代末，由于近海亚音速或超音速掠海飞行反舰导弹威胁的不断增加，水面舰艇急需装备一种能在强杂波环境下有效探测反舰导弹的雷达。 因此，美海军研究实验室雷达分部于1991年提出研制 AN/SPQ-9B 雷达。 要求这种雷达能够提供一种全新的低 …

The AN/SPQ-9B scans out to the horizon and performs simultaneous and automatic air and surface target detection and tracking of low flying Anti-Ship Cruise Missiles (ASCMs), surface threats, and...

The upgraded SPQ-9B - which uses a high-resolution, track-while-scan, X band, pulse- Doppler radar - will enable detection and establishing firm track ranges on subsonic and supersonic sea-skimming missiles. The system concept includes a new air mode that provides a new, low-cost, quality sea-skimmer detection capability and a surface mode with ...

The AN/SPQ-9B provides raw and clear plot (processed) surface video, processed radar air synthetic video, gate video, beacon video synchro signals indicating antenna relative azimuth, Azimuth Reference Pulses (ARP), and Azimuth Change Pulse (ACP).

The AN/SPQ-9B is a multimode X-band pulse Doppler radar that detects all known and projected sea skimming missiles. The multimission radar is designed to detect small, fast-moving targets in the presence of clutter from ocean waves, rain and land returns, as well as chaff and jamming.

The AN/SPQ-9B detects sea skimming missiles at the horizon even in heavy clutter while simultaneously providing detection and tracking of surface targets and beacon responses. The AN/SPQ-9B is available as a stand-alone radar or as a replacement for the AN/SPQ-9 in the Mk 86 Gun Fire Control System, which will be integrated into the Mk 1 Ship ...
